The presence of at least one asymmetric carbon atom in the compounds of formula I means that the compounds may occur in optically isomeric and enantiomeric forms. As a result of the presence of a possible aliphatic C═C double bond, geometric isomerism may also occur. Formula I is intended to include all those possible isomeric forms and mixtures thereof. Where no specific isomer is specified the mixtures of diastereomers or racemat is meant, as obtainable from the synthesis methods.

Certain mandelic acid derivatives have been proposed for controlling plant-destructive fungi (for example in WO 94/29267 in WO 96/17840 and in PCT/EP01/05530). The action of those preparations is not, however, satisfactory in all aspects and needs of the agricultural practices. Surprisingly, with the compound structure of formula I, new kinds of microbiocides having a high level of activity have been found.

Some of the compounds of formula I are described in the literature as pharmacologically active compounds. Though they have now been found to be useful as plant protectants, these compounds will not be subject of the group of claimed novel compounds. The known pharmacologically active compounds falling within the scope of formula I have been isolated as natural products and disclosed by G. R. Pettit et al. in J. Nat. Prod, 1996, (59), pp. 927-934. In this disclosure the compounds are designated as Hemibastadinols, and have the chemical designations follows:

-   2-hydroxy-N-[2-(3-bromo-4-hydroxy-phenyl)-ethyl]-3-(3-bromo-4-hydroxy-phenyl)propionamide, -   2-hydroxy-N-[2-(3-bromo-4-methoxy-phenyl)-ethyl]-3-(3-bromo-4-methoxy-phenyl)propionamide, -   2-hydroxy-N-[2-(3-bromo-4-methoxy-phenyl)-ethyl]-3-(3,5-dibromo-4-hydroxy-phenyl)propionamide, -   2-hydroxy-N-[2-(3,5-dibromo-4-hydroxy-phenyl)-ethyl]-3-(3-bromo-4-hydroxy-phenyl)propionamide, -   2-hydroxy-N-[2-(3,5-dibromo-4-methoxy-phenyl)-ethyl]-3-(3-bromo-4-methoxy-phenyl)propionamide,     and -   2-hydroxy-N-[2-(3-bromo-4-methoxy-phenyl)-ethyl]-3-(3,5-dibromo-4-methoxy-phenyl)propionamide.

The compounds of formula I may be obtained according to one of the processes of Schemes 1 to 5:

The compounds of formula I are oils or solids at room temperature and are distinguished by valuable microbiocidal properties. They can be used in the agricultural sector or related fields preventatively and curatively in the control of plant-destructive microorganisms. The compounds of formula I according to the invention are distinguished at low rates of concentration not only by outstanding microbiocidal, especially fungicidal, activity but also by being especially well tolerated by plants.

Surprisingly, it has now been found that the compounds of formula I have for practical purposes a very advantageous microbiocidal spectrum in the control of phytopathogenic microorganisms, especially fungi. They possess very advantageous curative and preventive properties and are used in the protection of numerous crop plants. With the compounds of formula I it is possible to inhibit or destroy phytopathogenic microorganisms that occur on various crops of useful plants or on parts of such plants (fruit, blossom, leaves, stems, tubers, roots), while parts of the plants which grow later also remain protected, for example, against phytopathogenic fungi.

The novel compounds of formula I prove to be effective against specific genera of the fungus class Fungi imperfecti (e.g. Cercospora), Basidiomycetes (e.g. Puccinia) and Ascomycetes (e.g. Erysiphe and Venturia) and especially against Oomycetes (e.g. Plasmopara, Peronospora, Pythium and Phytophthora). They therefore represent in plant protection a valuable addition to the compositions for controlling phytopathogenic fungi. The compounds of formula I can also be used as dressings for protecting seed (fruit, tubers, grains) and plant cuttings from fungal infections and against phytopathogenic fungi that occur in the soil.

The invention relates also to compositions comprising compounds of formula I as active ingredient, especially plant-protecting compositions, and to the use thereof in the agricultural sector or related fields.

In addition, the present invention includes the preparation of those compositions, wherein the active ingredient is homogeneously mixed with one or more of the substances or groups of substances described herein.

In the above mentioned mixtures, the mixture ratio of the active ingredients is so selected that it reaches optional control of the phytopathogenic microorganism on the host plants. This ratio is in general between 100:1 and 1:100, more preferably between 10:1 and 1:10 of a compound of formula I vis-à-vis the second fungicide. The mixtures may not only comprise one of the listed combinational active ingredients, but may comprise more than one additional active ingredients selected from that specified group, thus forming for example 3-way- or even 4-way-mixtures.

Suitable carriers and surfactants may be solid or liquid and correspond to the substances ordinarily employed in formulation technology, such as e.g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilisers. Such carriers and additives are described, for example, in WO 95/30651.

A preferred method of applying a compound of formula I, or an agrochemical composition comprising at least one of those compounds, is application to the foliage (foliar application), the frequency and the rate of application depending upon the risk of infestation by the pathogen in question. The compounds of formula I may also be applied to seed grains (coating) either by impregnating the grains with a liquid formulation of the active ingredient or by coating them with a solid formulation.

The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in formulation technology, and are for that purpose advantageously formulated in known manner e.g. into emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, diluter emulsions, wettable powders, soluble powders, dusts, granules, and by encapsulation in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.

Advantageous rates of application are normally from 1 g to 2 kg of active ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kg a.i./ha, especially from 25 g to 750 g a.i./ha. When used as seed dressings, rates of from 0.001 g to 1.0 g of active ingredient per kg of seed are advantageously used.

The formulations, i.e. the compositions, preparations or mixtures comprising the compound(s) (active ingredient(s)) of formula I and, where appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredient with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
